Brother Monks, I've Super Searched, I've Googled, and I've played with the smallest possible program (below) I could build, but I haven't been able to find how to deterime the size of a reference to an array (not a hash)
use strict;
my @Header =
(
'Record Type ',
'File Generation Date/Time ',
'Origin ',
);
my @New;
my @Trailer;
my %Classes = (
'NW' => { labels => \@New },
'HD' => { labels => \@Header },
'TR' => { labels => \@Trailer },
);
my $type = 'HD';
Display( $Classes{ $type }->{labels} );
sub Display
{
my ( $Labels ) = @_;
my $count = scalar( $Labels ); ### I know this doesn't work.
print sprintf( "Display: %d '%s'\n", $count, $Labels->[1] );
}
I realize if I was using an array (rather than an array reference) I could use
$#name or
scalar( @Name ).
Unfortunately, I need to use the contents of
@Header sequentially, so using a hash isn't an option.
Thank you for your help in advance.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
